This is the view from the red star in
Aerial Photo No. 4.
We are looking almost due south along the Holai Pali. It's easy to
see the step faults going down towards the left in this image.
Believe it or not, walking down this part of the Chain of Craters Road
is actually one of the best "adventure walks" that a visitor can
take. As long as you have good boots, long trousers (to prevent
scrapes), and a strong pair of gloves (protect your hands too), you
can slowly pick your way down this 300 meter-high cliff. If you do
this walk, you'll get a fascinating close-up view of many of the lava
flows. But, as always, be careful, this is very steep country and the
footing is never steady!

One of the neat things about the Mauna Ulu lava flows is that they
formed such interesting patterns as they cooled. Here we see a series
of pahoehoe lava "ropes", with the b/w ruler (in 5 cm intervals) for
scale.

Everything seems to have gone wrong for the lava flow when it tried
to go over almost vertical parts of the Holai Pali. Here we see just
one example of hundreds of small flow lobes that came down right where
the road is now located.
